Description

The 330930-065-02-05 is a rugged, industrial-grade 3300 XL NSv Extension Cable manufactured by Bently Nevada (a Baker Hughes business). This specialized cable provides critical low-loss signal connectivity within the 3300 XL NSv Proximity Transducer System, linking an NSv eddy-current probe to a 3300 XL NSv Proximitor Sensor. This sensor system is purposefully optimized for tight installation environments—such as centrifugal air compressors, refrigeration compression skids, and process gas machinery—where restricted side-view clearances or counterbore gaps limit the use of standard proximity sensors.

The complete option code 330930-065-02-05 defines its exact mechanical shielding and environmental defenses. This variant features a 6.5-meter (21.3 feet) cable length. It is protected by flexible stainless steel armor without an outer fluorinated ethylene propylene (FEP) insulation jacket, striking an ideal balance between severe abrasion resistance and physical routing flexibility in tight conduit runs. It is also factory-configured with Multiple Agency Approvals, rendering it fully compliant for deployment in classified hazardous plant areas around the globe.

Features

• Seamless electrical and mechanical backward compatibility with legacy Bently Nevada 3300 RAM proximity probe systems.
• Premium stainless steel armor safeguarding the internal coaxial core from physical pinching, cutting, or field crush hazards.
• Factory-terminated, gold-plated brass ClickLoc connectors that securely click into place to prevent industrial vibration from loosening connections.
• Specialized high-stability low-impedance coaxial core preserving high-frequency signal fidelity and scale factor accuracy.
• Multiple hazardous area agency certifications ensuring seamless, safe deployment across global refinery and oil & gas assets.

Applications

• Transferring critical dynamic vibration waveforms from narrow-clearance fluid-film bearing paths to central monitoring racks.
• Interconnecting axial thrust displacement probes located inside small-shaft turbomachinery assemblies.
• Relaying precise tachometer, speed-sensing, and Keyphasor phase reference signals from small rotating targets.

Installation Guidelines

• Total Loop Matching Rule: Always match this 6.5-meter extension cable with a compatible 0.5-meter proximity probe to achieve the exact 7.0-meter total loop system calibration length required by the 3300 XL NSv Proximitor Sensor. Mis-matching system lengths causes severe scale factor distortion.
• Minimum Cable Bend Radius: Avoid sharp bends or kinks during field installation. Maintain a minimum bend radius of 25.4 mm (1.0 in) to protect the inner coaxial shield and armor from structural fatigue.
• Connector Weatherproofing: After clicking the coaxial joints firmly together, slip dedicated male/female connector protectors or a layer of self-fusing silicone tape over the junction points to seal against moisture ingress and prevent structural grounding shorts.
• Conduit Protection Routing: Route the armored cable away from high-voltage AC motor power lines or heavy variable frequency drive (VFD) paths to prevent stray electro-magnetic noise from coupling onto the vibration signal.
